The Grand Mac will have two beef patties that total one-third pound of meat, according to a news release. The Mac Jr. will be just a single-layer burger.

The traditional sandwich has two all-beef patties, special sauce, lettuce, cheese, pickles and onions on a sesame seed bun.

“We listened to our customers who told us they wanted different ways to enjoy the one-of-a-kind Big Mac taste,” McDonald’s Chef Mike Haracz said. “The classic combination of ingredients remains timeless and customers around the world continue to enjoy its signature taste.”
